FIELD OF THE INVENTION

The present invention relates to strut channel fittings, and more particularly, to magnetic strut channel fittings configured to be magnetically adhered to a strut channel during assembly.

BACKGROUND OF THE INVENTION

Strut channels are generally used for structural supports, such as supporting cables and mechanical/electrical components, during construction of various facilities or buildings. For example, strut channels can be assembled together to make various shelves, racks, and other support structures and assemblies. These strut channels are generally secured together with strut channel fittings. Currently, the strut channel fittings are held in place manually (using hands) during assembly and secured to the strut channels with fasteners such as bolts. Since the strut channel fittings need to be lined up correctly against open ends of the strut channels while tightening bolts through the strut channel fittings, it is often time consuming and difficult to mount the strut channel fittings to join multiple strut channels.

Accordingly, although various strut channel fittings are available currently in the market, further improvements are possible.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

According to an embodiment of the present invention, referring to FIGS. 1-5, a magnetic strut channel fitting 10 includes a first plate 12, a second plate 14, and a plurality of magnets 16 embedded into at least one of the first and second plates 12, 14, as will be described in greater detail below. The magnetic strut channel fitting 10 is configured and adapted to be easily and conveniently mounted to strut channels 18, 20. More specifically, the plurality of magnets 16 allow the magnetic strut channel fitting 10 to magnetically adhere to the strut channel 18, as shown in FIG. 1, thereby, allowing an installer to freely use both hands during assembly to secure the magnetic strut channel fitting 10 to the strut channels 18, 20.

Referring again to FIGS. 1-5, the first and second plates 12, 14 are substantially flat and rectangular, and are connected to each other such that they are preferably perpendicular to each other. Alternatively, the first and second plates 12, 14 are connected such that an acute angle (e.g. 45 degrees) or an obtuse angle (e.g., 135 degrees) is formed between the plates 12, 14. In the depicted embodiment, the first and second plates 12, 14 are integrally connected to each other; alternately, the first and second plates 12, 14 could be welded thereto or attached via some other means. Preferably, first plate width FPW and second plate width SPW are equal to the width SCW of each of the strut channels 18, 20 such that, when the magnetic strut channel fitting 10 is mounted to the strut channels 18, 20, side edges 22, 24, 26, 28 of the first and second plates 12, 14 are flush with side walls 30, 32 of the strut channels 18, 20, as shown in FIG. 1. In addition, the length SPL of the second plate 14 is slightly greater than the length FPL of the first plate 12, although other configurations and dimensions are possible.

In the depicted embodiment, a plurality of magnet holes 34 are defined on the first plate 12, through which the plurality of magnets 16 are inserted and secured therewithin to allow the magnetic strut channel fitting 10 to be magnetically adhered to the strut channel 18 during assembly, as illustrated in FIG. 1. Specifically, the plurality of magnet holes 34 are positioned along each side portion of the first plate 12 such that the plurality of magnets 16 could be aligned and magnetically adhered to inturned members 36, 38 of the strut channel 18. Alternately, the plurality of magnet holes 34 could be defined on the second plate 14 or on both the first and second plates 12, 14.

Referring more particularly to FIG. 2, the plurality of magnets 16 are staked into the plurality of magnet holes 34. After the plurality of magnets 16 are installed into the plurality of magnet holes 34, the staking operation is performed to define a plurality of indents 40, with each indent 40 surrounding each corresponding magnet hole 34. Each of the plurality of indents 40 creates an interference fit between the first plate 12 and each of the plurality of magnets 16, thereby providing stability for each of the plurality of magnets 16. Alternately, the plurality of magnets 16 could be firmly secured within the plurality of magnet holes 34 by using an adhesive such as glue or some other means, as illustrated in FIG. 3. The plurality of magnets 16 are firmly embedded within the plurality of magnet holes 34 such that they do not move even a heavy axial load is applied thereon.

Each of the plurality of magnets 16 is dimensioned to be closely accommodated within each of the plurality of magnet holes 34. For example, the thickness of each of the plurality of magnets 16 is equal to the thickness of the first plate 12 such that each opposite end of each magnet 16 is flush with each surface of the first plate 12. This allows the magnetic strut channel fitting 10 to be installed in multiple orientations and also does not affect the interface between the magnetic strut channel fitting 10 and the strut channels 18, 20.

Referring again to FIGS. 1-5, each of the first and second plates 12, 14 includes a plurality of mounting holes 42, through which a fastener such as a bolt could be inserted and tightened with appropriate hardware to affix the magnetic strut channel fitting 10 to the strut channels 18, 20.

Preferred dimensions believed to be suitable for the magnetic strut channel fitting 10 include the first plate width FPW of approximately 1.625 inches, the second plate width SPW of approximately 1.625 inches, and the first and second plate lengths FPL, SPL of approximately 3.125 inches and 3.75 inches, respectively. The diameter of each of the plurality of magnets 16 and the diameter of each of the plurality of mounting holes 42 are preferably 0.25 inch and 0.56 inch, respectively.

Referring to FIGS. 6-9, in an alternate embodiment, a magnetic strut channel fitting 110 includes substantially flat first and second plates 112, 114, each having one mounting hole 116. In addition, the length of the first plate 112 is slightly greater than the length of the second plate 114, although other configurations and dimensions are possible.

Referring to FIGS. 10-12, in an alternate embodiment, a magnetic strut channel fitting 210 includes a substantially flat connecting plate 212, and L-shaped first and second arm members 214, 216, each having a vertical plate 218 and a horizontal plate 220. The first and second arm members 214, 216 are connected and separated by the connecting plate 212, defining a channel insert area 222 therebetween. A plurality of magnet holes 224 are defined on the connecting plate 212, through which a plurality of magnets 226 are inserted and secured therewithin to allow the magnetic strut channel fitting 210 to be magnetically adhered to a first strut channel 228 during assembly, as illustrated in FIG. 12. Specifically, the plurality of magnets 226 are positioned at each corner portion of the connecting plate 212 such that they could be aligned and magnetically adhered to inturned members 230, 232 of the first strut channel 228. A plurality of mounting holes 234 are defined on the first arm member 214, second arm member 216, and connecting plate 212, through which a fastener such as a bolt could be inserted and tightened with appropriate hardware to affix the magnetic strut channel fitting 210 to the strut channels 228, 236.

The magnetic strut channel fitting 210 is dimensioned such that a part of the first strut channel 228 could be closely accommodated within the channel insert area 222, as shown in FIG. 12. Once the magnetic strut channel fitting 210 is magnetically adhered to the first strut channel 228, a side edge 240 of the vertical plate 218 of each arm member 214, 216 and side edge 244 of the horizontal plate 220 of each arm member 214, 216 are flush with side walls 246, 248 of the first strut channel 228 and a side wall 252 of the second strut channel 236, respectively.

It will be appreciated that other shapes, configurations and dimensions could be used fir the magnetic strut channel fitting, as deemed suitable for a given application factors such as construction type. For example, in an alternate embodiment, referring to FIGS. 13-21, a magnetic strut channel fitting 310, 410, 510 is a substantially flat plate having a L shape (FIGS. 13-15) 312, a T shape (FIGS. 16-18) 412 or a square shape (FIGS. 19-21) 512. One or more mounting holes 314, 414, 514 and the plurality of magnet holes 316, 416, 516, with the plurality of magnets 318, 418, 518 embedded therewithin via staking (FIGS. 13, 16, and 19) or other suitable method (FIGS. 14, 17, and 21), are defined on the plates 312, 412, 512. The plurality of magnets 318, 418.518 are configured and positioned such that they could be aligned and magnetically adhered to inturned members 320, 322, 420, 422 of a strut channel 324, 424, as illustrated in FIGS. 15 and 18. A fastener could be inserted and tightened through the mounting hole 314, 414, 514 to affix the magnetic strut channel fitting 310, 410, 510 to the strut channel 324, 424.

The thickness of each of the plurality of magnets 318, 418, 518 is equal to the thickness of the plate 312, 412, 512 such that, when the plurality of magnets 318, 418, 518 are embedded into the plurality of magnet holes 316, 416, 516, each opposite end of each of the plurality of magnets 316, 416, 516 is flush with each surface of the plate 312, 412, 512.

The magnetic strut channel fitting 10, 110, 210, 310, 410, 510 is made out of one or more materials having suitable properties for a desired application, including strength, weight, rigidity, etc. Preferably, the plurality of magnets 16, 226, 318, 418, 518 are rare earth disc magnets. Additionally, steel is generally preferred for the plates 12, 14, 112, 114, 212, 218, 220, 312, 412, 512. The magnetic strut channel fittings 10, 110, 210, 310, 410, 510 are formed as unitary pieces; for example by stamping from a single sheet of metal.

From the foregoing, it will be appreciated that a magnetic strut channel fitting according to the present invention magnetically adheres to a strut channel during assembly, thereby providing faster and easier installation of strut channels.
